abstract = {In these days, enterprises are more and more confronted to fast changing and
turbulent markets. In order to remain competitive, they have to quickly adapt
themselves to these new situations. The integration solutions employed in such
an environment enable the required agility, by using a loose and flexible
integration architecture. We propose an integration solution based on the
concept of propagating data changes from one information system to the affected
information systems. This paper focuses on the question: how data from other
data services can be accessed and exploited to enhance a data change
propagation system. These services are based on a service-oriented architecture
(SOA) using XML technologies (e.g. SOAP). We developed the Data Service
Description Language (DSDL) to define the data structures of the data service.
This description is used to create the above mentioned Transformation Scripts
as well as to generate requests for accessing remote data. A layered system
approach is introduced to facilitate both the architecture and its
implementation.},

abstract = {The development of successful new products and services in highly dynamic
business environments has become an extremely difficult task. Innovation
managers have to utilize a considerable amount of enterprise-internal and
enterprise-external information to judge the potential of new products,
services and technologies.
Scenario management is a powerful instrument to face this problem. Scenarios
represent an intuitive concept to comprehend complex present-day and future
situations. The scenario technique is a method for building such scenarios.
Assessments of future business environments relying on structured scenarios
enable innovation managers to target lucrative market segments and to select
promising product ideas. However, diverse enterprise-internal and
enterprise-external resources have to be utilized to assist the scenario
development process. Last but not least, existing methods are often extremely
time-consuming and existing tools for scenario development fail to provide a
comprehensive solution as they are limited to certain steps in fixed workflows.
In this paper, we propose a modular web-based framework for the flexible and
efficient development and handling of scenarios. Key aspects of our framework
are module-based enterprise-specific workflows, the integration of distributed
human resources into the scenario development process and diverse interfaces to
enterprise-internal and enterprise-external information sources. The framework
is based on self-contained software modules that cover important steps of the
scenario management process. This modularity allows the easy supplementation of
existing 'scenario technique' methods with newly developed methods that are
incorporated into modules and can be combined in a flexible way to fit
enterprise-specific requirements.},

to be able to respond quickly to both external and internal changes. This
includes the ability to plan the optimal factory configuration and the assembly

support manufacturing enterprises shortening planning time and increasing

Application Integration, a scenario is described, which reveals how a
transformable manufacturing enterprise reacts to market changes with the
support of digital tools. Motivated by our scenario we developed an integration
solution called Stuttgart Integration Platform. A main role in our approach
plays a solution for the Digital Factory, which stores all needed information
about the planned facility layouts and assembly processes. The paper presents
our central integration solution Champagne, and three integrated systems: the
Digital Factory Solution, the Factory Planning Table and the Assembly
Configuration Tool.},

abstract = {In this paper, we address the data management aspect of large-scale pervasive
computing systems. We aim at building an infrastructure that simultaneously
supports many kinds of context-aware applications, ranging from room level up
to nation level. This allembracing approach gives rise to synergetic benefits
like data reuse and sensor sharing. We identify major classes of context data
and detail on their characteristics relevant for efficiently managing large
amounts of it. Based on that, we argue that for large-scale systems it is
beneficial to have special-purpose servers that are optimized for managing a
certain class of context data. In the Nexus project we have implemented five
servers for different classes of context data and a very flexible federation
middleware integrating all these servers. For each of them, we highlight in
which way the requirements of the targeted class of data are tackled and
discuss our experiences.},

abstract = {Location-based applications need information that can be spatially accessed.
Typically, this data is exspecially gathered and preprocessed in a particular
way (e.g. in a spatial data base). Up to now most of these applications ignore
an existing large information space, the World Wide Web. Web pages can be
mapped to locations and then accessed by location-aware applications with
spatial predicates. We want to automate the process of mapping web pages to
locations because of the huge amount of data available in the WWW. Our web
robot DCbot analyses web pages using pre-defined rules and spatial knowledge
and maps them to locations. In the demonstration we will show some location
mapping results of DCbot and, in addition, we will let DCbot scan locally
stored web pages at demonstration time, so that effects of changes of the
content can be shown.},

abstract = {With the emerging availability of small and portable devices which are able to
determine their position and to communicate wirelessly, mobile and
spatially-aware applications become feasible. These applications rely on
information that is bound to locations and managed by so-called location-based
data services. Based on a classification of location-based data services we
introduce a service-oriented architecture that is built on a federation
approach to efficiently support location-based applications.},
